Hi, First of all, please advise me that Whether you backup your data to a network place? If so, you need to check your Network status. Please refer to the following link: http://social.answers.microsoft.com/Forums/en-US/w7repair/thread/a3a7883c-9b61-4eba-bb97-e1c62419f03d In addition, Do you have any third-party backup utility installed on your computer? Follow the methods listed below: Method 1: If you’re trying to backup to the private network using wireless connection, I’d suggest you to try and use a wired connection instead and try backing up the data. Few users have fixed the issue by using a wired connection to backup the data over a network. Method 2: Uninstall the third-party backup utility, if any and check if that fixes the issue. If you’re using a wired connection, start your computer in a clean boot state and perform the backup. Check if that fixes the issue. See How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7 for instructions.
